Samsung Tab S2 Recovery Help!

[AC Question]

Im new to andriod, coming from IOS and my friend thought he could root my device and told me it was similar to jailbreak on IOS. After using odin to install twrp and flash SuperSU.zip onto my device, it will not go past the boot screen and has at the top 'Set Warranty Bit : kernel'. I need to get back andriod here is the situation:

No backups
Team win installed on device (If that helps)
Able to access data via computer and Odin can connect but not when it is in downloading mode
I have all my important stuff on a sd card so I was able to recover that
System/bin folder is empty
Samsung Galaxy Tab 2 SM-T719Y
Have downloaded the Firmware
SuperSU root

screen says:

Boot-
Set warrant bit : kernal

Download-
ODIN MODE: (HIGH SPEED)
PRODUCT NAME: SM-T719Y
SYSTEM BINARY: CUSTOM

WARRANTY VOID: 0x1 (2)
QUALCOMM SECUREBOOT: ENABLE (CSB)

I just need Android back, so data loss isn't a worry. How can i do this in simple terms - Im a noob.
